#1 [14.8] A novel triple-mode sensor utilizing trimetallic derived fluorescent carbon dots nanozyme for tetracycline determination.

Tetracycline (TC) is notoriously resistant to degradation in natural environments, which contributes to its prolonged persistence and widespread contamination. Improper or excessive use of TC can lead to multifaceted hazards. In this study, we developed a trimetallic-doped carbon dots (Fe,Cu,Ce-CDs)-based composite that exhibits distinct fluores...

#2 [14.8] Self-powered photoelectrochemical aptasensor based on CHA-triggered G-quadruplex/hemin cascade for homogeneous detection of ochratoxin A in a separated-coupling electrolysis system.

To address the challenge of electroactive interferences derived from complex food matrices during homogeneous photoelectrochemical (PEC) biosensing, a "separated-coupling" electrolysis platform was rationally engineered for the ultrasensitive detection of ochratoxin A (OTA). Based on the analysis of the conduction band of the α-Fe2O3 photoanode ...

#3 [13.8] A bimetallic metal-organic framework-based aptasensor for dual-mode colorimetric and fluorescent detection of Fumonisin B(1).

Fumonisin B1 (FB1) is a secondary metabolite produced by Fusarium species and is considered one of the most dangerous mycotoxins. It is widely present in maize and other agricultural commodities, posing severe threats to human health and animal husbandry. Consequently, the development of a convenient and rapid detection method is of paramount im...

#4 [13.8] Au-Ag NFs@Pt NCs nanozymes-driven aptasensor for sensitive visual detection of aflatoxin B1 in peanut.

Nanozyme-based aptasensors still face challenges, including low catalytic activity and inverse signal correlation, which hinder their advancement in the field of food safety. To address these issues, this study developed a novel nanozyme-based colorimetric aptasensor for the high-performance detection of AFB1. Initially, a gold-silver alloy nano...

#5 [13.8] Ultra-sensitive acrylamide detection in potato chips extract based on carbon paste electrode modified with liposomes carrying ferrocene-labeled aptamer.

The rapid and sensitive detection of acrylamide in thermally processed food products has attracted significant scientific interest. Herein, we report a novel electrochemical aptasensor that integrates a ferrocene-labeled DNA aptamer within a liposome-based nanostructured interface for enhanced signal transduction. The sensing layer was construct...

#6 [12.8] A synergistically enhanced electrochemiluminescent aptasensor based on antenna effect and localized surface plasmon resonance for chloramphenicol assessment.

Chloramphenicol (CAP) is a serious antibiotic residue in milk that poses health risks to consumers, prompting the exploration of exceptionally responsive diagnostic techniques such as electrochemiluminescence (ECL). Lanthanide-based coordination polymers exhibit promising ECL via the intrinsic antenna effect, yet they suffer from low radiative d...

#7 [12.8] An integrated litmus test platform for low-background detection and photothermal inactivation of Salmonella typhimurium via HCR-urease signal amplification.

Herein, we propose a novel "low-background" biosensing platform integrating magnetic separation and hybridization chain reaction (HCR) for signal amplification, enabling ratiometric colorimetric detection and visual observation of S. typhimurium. In the presence of S. typhimurium, specific aptamer recognition triggers the HCR to couple the ureas...

#8 [12.1] Spatially confined programmable DNA hydrogel scaffolds accelerate Cas12a trans-cleavage for digital bioimaging.

Molecule diffusion limits target detection in conventional homogeneous solution, typically resulting in inefficient target-probe collision efficiency, low reaction kinetics, and insufficient signal accumulation. Herein, a dual rolling circle amplification-based DNA hydrogel was constructed to establish a hydrogel confined digital imaging platfor...

#9 [11.2] Deciphering fluorine-fluorine interaction in an AIE-active trifluoromethyl-COF for trifluralin detection in the food chain

#10 [10.4] Surface engineered nitrogen doped carbon quantum dots for mechanistic understanding and advanced biosensing of antibiotic contaminants: a review.

Nitrogen-doped carbon quantum dots (N-CQDs) have emerged as a versatile platform for antibiotic biosensing, yet the field has been hindered by empirical optimization without mechanistic understanding. This review establishes quantitative structure-property-performance relationships that enable rational sensor design. We demonstrate that surface ...
